It looks like a small tumor which are not uncommon on older dogs. If it has come up suddenly I would get her in to see your vet right away since aggressive cancers will pop up suddenly and change rapidly. Even if it is benign, if she is in good health it might be a good idea to have it removed so it doesn't get caught and injured by her day to day routine. Your vet will do an exam, possible sample some cells from it to try to identify it and bloodwork if you opt to remove it to determine her suitability for anesthesia. It looks from the photo like it would not be a complicated process to remove it.
